C.1 Regionalization Factor Bar Graph separately for 2018-19; 2019-20 (difference in regionalization factor levels between years): G1=1; men=average poverty rate; women=average share of students of color
C.2. Regionalization correlated with teacher salary adjusted local non-teacher wages (which is in the cost index database). Use either bar graph as above, or use the correlation scatter plot similar as below (regionalization factor will be in the x-axis, while average teacher salary for each district in 2019-20 [adjusted for local non-teacher wages] will be in the y-axis).
C.3. Poverty-level correlated with teacher salary adjusted local non-teacher wages (which is in the cost index database). use the correlation scatter plot similar as above in C.2 (poverty rate will be in the x-axis, while average teacher salary for each district for the average of 2018-19 and 2019-20 [adjusted for local non-teacher wages] will be in the y-axis). C.4. Share of Students of color is correlated with teacher salary adjusted local non-teacher wages (which is in the cost index database). use the correlation scatter plot similar as above in C.2 (percentage points of students of color will be in the x-axis, while average teacher salary for each district the average of 2018-19 and 2019-20 [adjusted for local non-teacher wages] will be in the y-axis).
C6. Teacher workforce (Racial/Ethnic composition, educational attainment and experiences), by Student (high-vs-low poverty; by high- vs. -low students of color).
C7. Line charts: Teacher turnover (/ teacher newcomers to the district per 1000 students; average experiences of teachers)= districts’ poverty rates
